After reading flyingmoose's reaction to merlyn's post, I wandered through the POD myself to see if any of the behaviors that merlyn discussed are in some way undocumented such that they should come as a surprise. In just about every case, I found what I was looking for. I thought I might as well offer a little more detail on the ones that seemed most interesting.

Regarding flyingmoose's dismay over the situation, and his call for improved consistancy, this came up awhile back in What should be returned in scalar context?. I think that the general consensus was that functions should return what it makes sense for them to return in scalar context. In other words, don't get too caught up in trying to make all list-oriented functions return the same thing in scalar context. Not every shoe fits every foot.

To call these behaviors bugs is irrational, since they, in most cases, are doing something useful, and something that's defined in the documentation. The suggestion to not make assumptions is spot-on; that's why the POD is there -- so assumptions don't have to be made.
